b42d3b159a drm/i915/display: cleanup intel_bw_state on i915 module removal 
intel_bw_state allocated memory is not getting freed even after
module removal.

kmemleak reported backtrace:

Call the drm_atomic_private_obj_fini(), which inturn calls the
intel_bw_destroy_state() to make sure the intel_bw_state memory is
freed properly.

366b6200f7 drm/i915/bw: make intel_atomic_get_bw_state() static 
No need for this function to be accessible outside of intel_bw.c. Avoid
including the i915_drv.h mega header from other header files to make
further header cleanup easier.

df0566a641 drm/i915: move modesetting core code under display/ 
Now that we have a new subdirectory for display code, continue by moving
modesetting core code.

display/intel_frontbuffer.h sticks out like a sore thumb, otherwise this
is, again, a surprisingly clean operation.

v2:
- don't move intel_sideband.[ch] (Ville)
- use tabs for Makefile file lists and sort them
